' I 3 Claim.

This invention appertains to new and useful improvements whereby cables can be slit in a quick and eflicient manner.

The principal object of the invention is to provide a slitter-which can be readily applied to a cable, to the end that the covering thereon can be easily slit for skinning thus simplifying the operation of skinning conductors which at present takes considerable time and i many times dangerous to the workman inasmuch as he must use a sharp instrument in a rather awkward mani Other objects and advantages of the inven- .tion will become apparent to the reader'of the following description.

I n the drawings:

Figure lrepresents a side elevational view of the slitter. v I Figure 2 is a top plan view.

Figure 3 is an end elevational view with tion in section.

Figure 4 is a cross se'ctionon the line l4 of Figure 2.

a por- Figure 5 is an elevational view showing the slitter in opened position.

Figure 6 i a fragmentary perspective view showing a filler for small size cables.

Figure 7 is a side elevatlonal view'of rotary type of slitter.

Figure 8 is a-fragmentary top plan view of the form of invention shown in Figure 7.

Referring to the drawings, wherein the same numerals designate the same parts, it can be seen that the slitter disclosed inFigures 1 to 5, inclusive, consists of a pair of elongated plate-like members 5, 6 of right angled cross section connected together at one side edge thereof by a hinge structure 1 for closing to form a box-like guide.- Wooden blocks 8, 9 are secured to the adjacent side portions of 'the members 5, 8 by screws or the like it! and are curved on their outer surfaces" so as to better conform with the hand of the user. one end of the angle member 5 has an outstanding boss II at its corner portion or angle-forming edge and this has'an open ing therethrough for receiving a cutter blade l2, the boss H having a set screw l3 .feedable into the boss and against the blade I! to hold the same in a definite position.

- as new is:

filler plate I 4 have end lugs l5 for engaging the ends of the angle member 6. to the end that the filler plate cannot move longitudinally in the device.

A rotary type of slitter is depicted in Figures 7 and 8 and this consists of a pair of angle members l6, I6 hingedly secured together at adjacent edges as at ll, while the opposite edges are provided with elongated handles l8, l8. One of the anglemembers l6 has an outstanding boss l9 formed with an opening for'receiving a blade 20, which, of course, will project into the opening through the device to cut into a cable covering as suggested in Figure 7. A set screw 2| can be driveninto the boss I9 to bite against the blade 20.

Obviously, in the tool shown in Figures '1 and a, r

the handles are rotated about a cable and this re- ,sults in slitting the cable covering clrcumferentially so that the covering can be easily pulled off of the conductor wire.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter. t

. Having described the invention, what is claimed 1. A cable slitting tool comprising a pair of cable embracing elements of elongated plate-like form and right-angled cross-section hingedly connected together at one side edge thereof for.

closing into box-like form, and a cutter element projecting inwardly from the angle-forming edge ot one of said elements.

2. A cable slitting tool comprising a pair 0 cable embracing elements of elongated plate-like form and right-angled cross-section hingedly connected-together at one side edge thereof for closing into box-like form, a cutter element projecting inwardly from the angle-forming edge of one of the cable embracing elements, and a filler plate removably disposable in the other cable embracing element and having right-angled ends Obviously, the device is placed arounda cable A and the blade I! forced into the insulation,

after which the device can be pulledalong the cable; thus slitting open the insulation or other covering so that the same may be easily removed. In the eventthe device is to be used with a plate ll may beplaced against the inner side of the angle member 6 to partly close the passageway through the device. It is preferable that the for engaging the ends of said other elements to prevent endplay of said filler plate relative to said other element.

3. A cable slitting tool comprising a. pair of cable embracing elements of elongated plate-like form and right-angled cross-section hinged together at one side edge thereof for closing into substantially small cable, an angle-shaped nus? box-like form, a cutter element projecting inwardly from the angle-forming edge of one of said elements, and a pair of elongatedhandles one projecting from each of the side edges of the elements.
